Embodiment 1

[0047] Embodiment 1 Ring needle sensor and control circuit

[0048] ring needle sensor such as figure 1 , 2 , shown in 3, encircle a large ring 102 with photodiodes VD101~VD172 on the plane board 101, separate with partition plate 104 between each photodiode; use photodiodes VD173~VD176 to enclose a A small ring 105 concentric with the large ring 102; each photodiode is also separated by a partition 104; a long pointer 115 is installed at the center of the small ring 105, and the center of the long pointer 115 is empty, which is a thin tube , to facilitate the passage of wires. The long pointer 115 is on the plane board 101 , and there is a relatively short short pointer 113 on the back of the plane board 101 . The center of the short pointer 113 is hollow, that is, a thin tube, which is convenient for the passing of the wire. A photodiode VD177 is mounted on the long pointer 115 port in front of the flat board 101. A photodiode VD178 is mounted on the short pointer 113 p...

Embodiment 2

[0058] Example 2 Tracking and Driving of Azimuth and Elevation

[0059] According to the geographical location of our country in the northern hemisphere, especially the longest sunshine time is from May to August every year, which is also the golden season for solar power generation. In high-latitude areas, the sunshine time is much longer than 12 hours a day, that is, the azimuth of the sun's trajectory is much greater than 180 degrees; in low-latitude areas south of the Tropic of Cancer, the elevation angle trajectory exceeds 90 degrees; Subzero (zero degrees in the horizontal plane). BACKGROUND OF THE INVENTION Neither azimuth nor elevation driving technical indicators can meet the requirements of high latitude, low latitude and high mountain areas at the same time.

[0060] Such as Figure 8 , 9 , 10, the driving range of the azimuth drive motor 80 is expanded to 340 degrees by the 180 degree of the background technology (in the electric azimuth mechanical part, the sem...

Embodiment 3

[0066] Embodiment 3 solar panel and support

[0067] Such as Figure 13 , 14 , 15 and 16, the solar panel 121 has the following features: the solar panel 121 is designed as a folding box 132, which is easy to carry and install. The shell 131 of the folding box 132 is made of aluminum alloy, which has the characteristics of light weight and high strength. The shell 131 of the solar cell panel 121 is equipped with a connecting plug 128, and the connecting plug 128 is fixed with the shell 131 with a rivet 129, which is convenient for connecting and fixing with the support 145, see Figure 14 , Figure 16 . Rubber strips 123 are inlaid on the outer frame 124 of the solar battery panel 121, so that the folding box 132 can effectively prevent the vibration and breakage of the solar battery panel 121 during transportation by car. And on the shell 131 of the folding box 132, four relatively hard rubber cylinders 130 are installed on the back of each solar panel 121. Prevent dama...

Abstract

The invention relates to a ring-needle sunlight tracking driving system of a car-mounted solar battery, which belongs to the technical field of solar application. The ring-needle sunlight tracking driving system comprises a solar panel, a latch, a decoder, a single chip microprocessor, an azimuth and elevation driving device and a ring-needle sensor (163); the sunlight information obtained by the ring-needle sensor is inputted to the single chip microprocessor through the latch and the decoder, and the azimuth and elevation driving device is controlled by the single chip microprocessor, so that the solar panel tracks the sunlight to provide the electric power. The ring-needle sensor is characterized in that photosensitive diodes are encircled to form a large ring (102) and a small ring (105) on a surface plate (101), and a separation plate (104) is arranged between two adjacent photosensitive diodes; the front surface and the back surface of the surface plate are respectively provided with a long pointer (115) and a short pointer (113), which are vertical to an installation end. The sensor is light in weight, small in size, small in air resistance and simple in structure; the azimuth and elevation synchronous tracking driving is realized, so that the tracking range completely covers a movement path of the sun.
